Description

Purpose

Di-Pentaerythritol as an important fine chemical intermediate, it is regarded as the middle and high end product of pentaerythritol, which is mainly used in high-end coatings industry. Production of polyether, polyester, polyurethane, high-grade alkyd resin and photosensitive resin film. Double season advanced fat used in advanced aviation lubricating oil, low fat can be used as PVC plasticizer, in terms of photosensitive coating, acrylic ester can be used as a double season stainless steel color plate, advanced granite spray mask, has strong adhesive force, friction resistance, ageing resistance excellent performance.

Physicochemical property

1.molecular weight:254.28

2.Stability: it is stable in the air and not easy to absorb

3.water solubility 0.29 G/100 ML (20 ºC)

4.Other physicochemical properties: slightly sweet, basically non-toxic

Manufacturing technique

Extract from the pentaerythritol reactive liquid mixture

Transport storage

When transported, it should be in a clean, clean, covered wagon or boat.

Should be stored in a dry, clean, ventilated warehouse, not in the open air.
